What technical requirements define polymer modified bitumen emulsion for asphalt or bitumen modification?
Polymer modified bitumen emulsion must meet specific technical requirements, including viscosity, stability, and adhesion properties. The emulsion should exhibit a stable particle size distribution and a minimum storage stability of 24 hours. Additionally, it should have a high polymer content (typically 3-10%) to enhance elasticity and temperature resistance. The emulsion’s pH should be neutral, and it must comply with relevant standards such as ASTM D6931 for performance and durability in asphalt applications.
